If any of the inmates at Yancheng prison are considering an escape attempt, they’d better do it soon. The Chinese prison is currently wrapping up months of construction on a new “smart” surveillance system designed to monitor prisoners at every moment, including while they are in their cells. According an official, this will make prison breaks virtually impossible — but it might also wreak havoc on prisoners’ psyches. According to the South China Morning Post, the facility is almost finished installing a network of cameras and sensors capable of constantly tracking inmates. These cameras and sensors will feed into an AI system that uses facial identification and movement analysis technologies to monitor each individual inmate at the Chinese prison, producing a daily report about each one and flagging any unusual behavior. “For instance,” project representative Meng Qingbiao told SCMP, “if an inmate has been spotted pacing up and down in a room for some time, the machine may regard the phenomenon as suspicious and suggest close-up checks with a human guard.” This isn’t the first example we’ve seen of prison officials attempting to make facilities “smart”. In February, Hong Kong’s Correctional Services Department announced the implementation of several technologies designed to help prisoners stay safe during their imprisonment. However, Zhang Xuemin, a physiology professor at Beijing Normal University, told SCMP the new system will “definitely affect” the prisoners’ mental state. And while he didn’t elaborate on what that effect might be, past research has shown that constant surveillance can increase a person’s stress and anxiety levels, while decreasing their trust in others — meaning the trade off for an escape-proof “smart” prison might be the mental health of its inmates.

Another critical factor that plays a part in susceptibility to colds is age. A study done by the University of Michigan School of Public Health revealed particulars that seem to hold true for the general population. Infants are the most cold-ridden group, averaging more than six colds in their first year. Boys have more colds than girls up to age three. After the age of three, girls are more susceptible than boy's , and teenage girls average three colds a year to boy’s two. The general incidence of continues to decline into maturity. Elderly people who are in good health have as few as one or two colds annually. One exception is founds among people in the twentics, especially women, who show a rise in cold infections, because people in this age group are most likely to have young children. Adults who delay having children until thirties forties experience the same sudden increase in cold infections. The study also found that economics play an important role. As income increases, the frequency at which are reported in the family decreases. Families with the lowest income suffer about a third more colds than families at the lower end. Lower income generally forces people to live in more cramped quarters than those typically occupied by wealthier by wealthier people, and crowding increses the opportunities for the cold virus totravel from person to person. Low income may also adversely influence diet. The degree to which poor nutrition affects susceptibility to colds is not yet clearly established, but an inadequate diet is suspected of lowering resistance generally.

In many aspects of life, effective communication skills are extremely important. With good communication skills, people can enjoy better interpersonal relationships with friends and family. The following are some guides that can help you improve your communication skills.

Learn to listen

Listening is not the same as hearing; you should learn to listen not only to the words being spoken but also how they are being spoken and the non-verbal messages sent with them. You shouldn't think about what to say next while listening; instead clear your mind and focus on the message being received. Your friends, colleagues and other acquaintances will appreciate your good listening skills.

Try to understand other people's emotions

To understand other people's emotions, you should be sympathetic to other people's misfortunes and congratulate them on their achievements. To do this, you need to be aware of what is going on in other people's lives. It's crucial to maintain eye contact and do not be afraid to ask others for their opinions as this will help to make them feel valued.

Encourage

It's advised that you offer words and actions of encouragement, as well as praise, to others, which make other people feel welcome, valued and appreciated in your communications. If you let others know that they are valued, they are much more likely to give you their best. You should also try to ensure that everyone get involved in an interaction or conversation by using effective body language and open questions.

What should we do to involve everyone in an interaction or conversation?

Having a best friend to confide in can bring a positive effect on our emotional health. An evening out with the closest friend may be the best guarantee of a good time. In fact, our best friend can prevent us from developing serious psychological problems such as depression and anxiety.

Best friendship evolves with time - we cannot go out and pick our best friend. We become friends with people who share common interests – at school or through hobbies, for example.

Best friends have usually known each other for years and stuck together through good and bad times. If you haven't got one, perhaps you are being too distant from people, or focusing too much on your work.

Close friends need to ________.

In 1959, the government of Egypt was working on a plan to build a dam on the River Nile. It was called the Aswan Dam, and it was intended to generate electricity and allow the river water to be used for agriculture. There was one big problem with the plan, though. The dam would flood a nearby valley that contained ancient Egyptian treasures, including two enormous stone temples.
It can be difficult for governments to choose culture and history over economics. However, if countries always made decisions like this, the majority of the world's ancient sites would end up being destroyed. Luckily, UNESCO stepped in. They formed a committee that tried to convince Egypt to protect its ancient treasures. With support from many countries, they were finally successful. The huge temples were carefully removed from their original site and moved to a safe location so that the dam could be built.

After their success in saving the temples in Egypt, UNESCO went on to save more sites around the world. They protected lagoons in Venice, ruins in Pakistan, and temples in Indonesia. With industrialisation changing the world rapidly, there were many sites that needed to be saved. Eventually, UNESCO formed the World Heritage Organisation to protect important natural and historic sites wherever it was necessary.

By now, the World Heritage Organisation has protected hundreds of sites ranging from beautiful natural islands to buildings in large cities and ancient ruins. If you're able to visit any of the many protected sites, you'll agree it was worth it.

 Why did UNESCO get involved in Egypt?

Many of the most damaging and life-threatening types of weather-torrential rains, severe thunderstorms, and tornadoes-begin quickly, strike suddenly, and dissipate rapidly, devastating small regions while leaving neighboring areas untouched. One such event, a tornado, struck the northeastern section of Edmonton, Alberta, in July 1987. Total damages from the tornado exceeded $ 250 million, the highest ever for any Canadian storm. Conventional computer models of the atmosphere have limited value in predicting short-live local storms like the Edmonton tornado, because the available weather data are generally not detailed enough to allow computers to discern the subtle atmospheric changes that precede these storms. In most nations, for example, weather balloon observations are taken just once every twelve hours at locations typically separated by hundreds of miles. With such limited data, conventional forecasting models do a much better job predicting general weather conditions over large regions than they do forecasting specific local events. Until recently, the observation-intensive approach needed for accurate, very short-range forecasts, or "Nowcasts", was not feasible. The cost of equipping and operating many thousands of conventional weather stations was prohibitively high, and the difficulties involved in rapidly collecting and processing the raw weather data from such a network were insurmountable. Fortunately, scientific and technological advances have overcome most of these problems. Radar systems, automated weather instruments, and satellites are all capable of making detailed, nearly continuous observation over large regions at a relatively low cost. Communications satellites can transmit data around the world cheaply and instantaneously, and modern computers can quickly compile and analyzing this large volume of weather information. Meteorologists and computer scientists now work together to design computer programs and video equipment capable of transforming raw weather data into words, symbols, and vivid graphic displays that forecasters can interpret easily and quickly. As meteorologists have begun using these new technologies in weather forecasting offices, Nowcasting is becoming a reality.

The ideas of John Dewey, philosopher and educator, have influenced American thought for over one hundred years. Dewey was born in Vermont in 1859, and throughout hi life he kept the respect for experience, individuality, and fair play that shaped the character of the nineteenth century Vermonter. He viewed his own life as a continuously reconstructive process with experience and knowledge building on each other. By the 1930s, Dewey had simplified his theory of experience to its essence. As the intellectual leader of the progressive schools, he asserted that there was danger in rejecting the old unless the new was rooted in a connect idea of experience. He held that experience is an interaction between what a person already knows and the situation at hand. Previous knowledge interacting with the present environment influences future experience. Dewey be1ieved that experience could not be equated with education because all experiences as not necessarily educative. Experience is educative only when it contributes to the growth of the individual, but it can be miseducative if it distorts the growth of further experience. It is the quality of experience that matters. Thus, productive experience is both the means and the goal of education. Furthermore, since education is a social process, truly progressive education involves the participation of the learner in directing the learning experience.During his long life, Dewey lectured and published prolifically. These writings were influential both during his lifetime and after his death at the age of ninety-two. He viewed his whole life as an experiment which would produce knowledge that would lead to further experimentation. The range and diversity of Dewey’s writings and his influence on society place him among American’s great thinkers.

According to Dewey, progressive education should include____.

Read the following passage and choose the best answer (A, B, C, D):
Butterflies are among the most extensively studied insects, an estimated 90 percent of the world's species have their scientific names. As a consequence, they are, perhaps, the best group of insects for examining patterns of terrestrial biotic diversity and distribution. Butterflies also have a favorable image with the general public. Hence, they are an excellent group for communicating information on science and conservation issues such as diversity. Perhaps the aspect of butterflies diversity that has received the most attention over the past century is the striking difference in species richness between tropical and temperate regions. For example, in 1875 one biologist pointed out the diversity of butterflies in the Amazon when he mentioned that about 700 species were found within an hour's walk, whereas the total number found on the British islands did not exceed 66, and the whole of Europe supported only 321. This early comparison of tropical and temperate butterflies' richness has been well confirmed. A general theory of diversity would have to predict not only this difference between temperate and tropical zones, but also patterns within each region, and how these patterns vary among different animal and plant groups. However, for butterflies, variation of species richness within temperate or tropical regions, rather than between them, is poorly understood. Indeed, comparisons of numbers of species among the Amazon basin, tropical Asia, and Africa are still mostly "personal communication" citations, even for vertebrates. In other words, unlike comparison between temperate and tropical areas, these patterns are still in the documentation phase. In documenting geographical variation in butterflies' diversity, some arbitrary, practical decisions are made. Diversity, number of species, and species richness are used synonymously; little is known about the evenness of butterfìy distribution. The New World butterflies make up the preponderance of examples because they are the most familiar species. It is hoped that by focusing on them, the errors generated by imperfect and incomplete taxonomy will be minimized

Fifty-five delegates representing all thirteen states except Rhode Island attended the Constitutional Convention in Philadelphia from May to September 1787. The delegates had been instructed by the Continental Congress to revise the old Articles of Confederation, but most believed that a stronger central government was needed. There were differences, however, about what structure the government should take and how much influence large states should have. Virginia was by far the most populous state, with twice as many as people as New York, four times as many as New Jersey, and ten times as many as Delaware. The leader of the Virginia delegation, James Madison, had already drawn up a plan for government, which became known as the Large State Plan. Its essence was that congressional representation would be based on population. It provided for two or more national executives. The smaller states feared that under this plan, a few large states would lord over the rest. New Jersey countered with the Small State Plan. It provided for equal representation for all states in a national legislature and for a single national executive. Angry debate, heightened by a stifling heat wave, led to deadlock. A cooling of tempers seemed to come with lower temperatures. The delegates hammered out an agreement known as the Great Compromise - actually a bundle of shrewd compromises. They decided that Congress would consist of two houses. The larger states were granted representation based on population in the lower house, the House of Representatives. The smaller states were given equal representation in the upper house, the Senate, in which each state would have two senators regardless of population. It was also agreed that there would be a single executive, the president. This critical compromise broke the logjam, and from then on, success seemed within reach.

A survey is a study, generally in the form of an interview or a questionnaire, which provides information concerning how people think and act. In the United States, the best-known surveys are the Gallup poll and the Harris poll. As anyone who watches the news during campaigns presidential knows, these polls have become an important part of political life in the United States.
North Americans are familiar with the many “person on the street” interviews on local television news shows. While such interviews can be highly entertaining, they are not necessarily an accurate indication of public opinion. First, they reflect the opinions of only those people who appear at a certain location. Thus, such samples can be biased in favor of commuters, middle-class shoppers, or factory workers, depending on which area the news people select. Second, television interviews tend to attract outgoing people who are willing to appear on the air, while they frighten away others who may feel intimidated by a camera. A survey must be based on a precise, representative sampling if it is to genuinely reflect a broad range of the population.
In preparing to conduct a survey, sociologists must exercise great care in the wording of questions. An effective survey question must be simple and clear enough for people to understand it. It must also be specific enough so that there are no problems in interpreting the results. Even questions that are less structured must be carefully phrased in order to elicit the type of information desired. Surveys can be indispensable sources of information, but only if the sampling is done properly and the questions are worded accurately.
There are two main forms of surveys: the interview and the questionnaire. Each of these forms of survey research has its advantages. An interviewer can obtain a high response rate because people find it more difficult to turn down a personal request for an interview than to throw away a written questionnaire. In addition, an interviewer can go beyond written questions and probe for a subject’s underlying feelings  and reasons. However, questionnaires have the advantage of being cheaper and more consistent.

Read the following passage and choose the best answer (A, B, C, D):
Light from a living plant or animal is called bioluminescence, or cold light, to distinguish it from incandescence or heat-generating light. Life forms could not produce incandescent light without being burned. Their light is produced in chemicals combining in such a way that little or no measurable heat is produced, and the life forms generating it are unharmed. Although bioluminescence is a relatively complicated process, it can be reduced to simple terms. Living light occurs when luciferin and oxygen combine in the presence of luciferase. In a few cases, fireflies the most common, an additional compound called ATP is required. The earliest recorded experiments with bioluminescence in the late 1800s are attributed to Raphael Dubois, who extracted a luminous fluid from a clam, observing that it continued to glow in the test tube for several minutes. He named the substance luciferin, which means “the bearer of life”. In further research, Dubois discovered that several chemicals were required for bioluminescence to occur. In his notes, it was recorded that a second important substance, which he called luciferase, was always present. In later study of small, luminous sea creatures, Newton Harley concluded that luciferin was composed of carbon, hydrogen, and oxygen, which are the building blocks of all living cells. He also proved that there are a variety of luciferin and luciferase, specific to the plants and animals that produce them. Much remains unknown, but many scientists who are studying bioluminescence now believe that the origin of the phenomenon may be traced to a time when there was no oxygen in the Earth’s atmosphere. When oxygen was gradually introduced to the atmosphere, it was actually poisonous to life forms, plants and animals produced light to use up the oxygen in a gradual but necessary adaptation. It is speculated that millions of years ago, all life may have produced light to survive. As the millennia passed, life forms on Earth became tolerant of, and finally dependent on oxygen, and the adaptation that produced bioluminescence was no longer necessary, but some primitive plants and animals continued to use the light for new functions such as mating or attracting prey.

Read the passage below and anwser the following question.

"Let's see if you can correctly answer the following question: At what age are Latter-day Saint youth allowed to date? Of course, you probably immediately said, "16". OK, then, how about this one: At what age are you allowed to have a boyfriend or girlfriend? You may be thinking, “Um, 16. Didn't I just answer that?" Well, if that was your answer, then, even though you aced the first question, you missed the second one. Just because you can date when you turn 16 doesn't mean you should immediately start looking for a steady boyfriend or girlfriend.

To begin with, there are two different types of dating: casual dating and steady (or serious) dating. The distinction between the two has to do with exclusivity. With casual dating, there is no exclusivity. The two people aren't “a couple” or “an item”, and they don't refer to each other as a “boyfriend” or “girlfriend”. They don't pair off. People who are casually dating are simply friends. This is the kind of dating the Church encourages you to do after you turn 16. You should put aside a need to find a “one and only”. If you're dating casually, you don't expect a relationship to become a romance. You have fun; you do a variety of things with a variety of people. On the other hand, steady dating means the couple is exclusive with one another. They expect each other not to date anyone else or to be emotionally or physically close with other people. Couples who date seriously consider the future, because there is a real possibility they could stay together. This is the kind of dating the Church encourages young adults (generally, people in their 20s) to progress toward, because that's the age when they should be thinking of marrying."

Read the following passage and choose the best answer (A, B, C, D):
There are many theories about the beginning of drama in ancient Greece. The one most widely accepted today is based on the assumption that drama evolved from ritual. The argument for this view goes as follows. In the beginning, human beings viewed the natural forces of the world, even the seasonal changes, as unpredictable, and they sought, through various means, to control these unknown and feared powers. Those measures which appeared to bring the desired results were then retained and repeated until they hardened into fixed rituals. Eventually stories arose which explained or veiled the mysteries of the rites. As time passed some rituals were abandoned, but the stories, later called myths, persisted and provided material for art and drama. Those who believed that drama evolved out of ritual also argue that those rites contained the seed of theater because music, dance, masks, and costumes were almost always used. Furthermore, a suitable site hard to be provided for the performances, and when the entire community did not participate, a clear division was usually made between the “acting area” and the “auditorium”. In addition, there were performers, and since considerable importance was attached to avoiding mistakes in the enactment of rites, religious leaders usually assumed that task. Wearing masks and costumes, they often impersonated other people, animals, or supernatural beings, and mimed the desired effect- success in hunt or battle, the coming rain, the revival of the Sun as an actor might. Eventually such dramatic representations were separated from religious activities. Another theory traces the theater’s origin from the human interest in storytelling. According to this view, tales (about the hunt, war or other feats) are gradually elaborated, at first through the use of impersonation, action, and dialogue by a narrator and then through the assumption of each of the roles by a different person. A closely related theory traces theater to those dances that are primarily rhythmical and gymnastic or that are imitation of animal movements and sounds.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

   It is commonly believed in the United States that school is where people go to get an education. Nevertheless, it has been said that today children interrupt their education to go to school. The distinction between schooling and education implied by this remark is important.

   Education is much more open-ended and all-inclusive than schooling. Education knows no bounds. It can take place anywhere, whether in the shower or on the job, whether in a kitchen or on a tractor. It includes both the formal learning that takes place in schools and the whole universe of informal learning. The agents of education can range from a revered grandparent to the people debating politics on the radio, from a child to a distinguished scientist. Whereas schooling has a certain predictability, education quite often produces surprises. A chance conversation with a stranger may lead a person to discover how little is known of other religions. People are engaged in education from infancy on. Education, then, is a very broad, inclusive term. It is a lifelong process, a process that starts long before the start of school, and one that should be an integral part of one's entire life.

   Schooling, on the other hand, is a specific, formalized process, whose general pattern varies little from one setting to the next. Throughout a country, children arrive at school at approximately the same time, take assigned seats, are taught by an adult, use similar textbooks, do homework, take exams, and so on. The slices of reality that are to be learned, whether they are the alphabet or an understanding of the workings of government, have usually been limited by the boundaries of the subject being taught. For example, high school students know that they are not likely to find out in their classes the truth about political problems in their communities or what the newest filmmakers are experimenting with. There are definite conditions surrounding the formalized process of schooling.
